Definitions
- the present invention relates to a rotary tiller device adapted for use for the plowing or tilling the soil, grading or leveling the ground, weeding, etc., and particularly concerned with the type of device in which oblique submerged reverse deep rotary tillage is used.
- Soil tillage is a heavy-duty work and consumes a lot of energy.
- plowing and rotary tillage are two main ways of soil tillage. By cutting soil orderly, plowing has good tillage performance and meets the demands for deep tillage.
- the plowed soil needs to be more harrowed, so, the tilling process is complicated, inefficient, energy-consuming and costly.
- Rotary tillers have both functions of plowing and harrowing. Meanwhile, it can till stubble, weeds, and green manure crops. Additionally, the tilled land remains level, and furrow slices are fragmented enough after rotary tilling.
- rotary tilling can meet the agronomic requirements and race against tillage time.
- rotary tillage needs more energy, and its performance coverage is relatively poorer compared to plow tillage. So, it can make many plants on the topsoil and let weeds sprout earlier.
- cultivation techniques are also used in rhizome crop cultivation.
- the quality of the cultivated soil is required more critically.
- tillage should increase the depth of tillage and make the soil looser.
- improving soil aeration, increasing the water capacity and making more straws returned to the field it is one of the leading research directions to increase the tillage depth, reduce energy consumption and improve tilling quality.
- the target tilling depth H is determined depending on the agronomic requirements, and cutter radius R is decided by R ⁇ H ⁇ ( ⁇ 1).
- ⁇ the value of rotational speed ratio of rotary tillage
- ⁇ the value of rotational speed ratio of rotary tillage
- the value of ⁇ should take a larger value.
- the value of R is relatively small, and consequently, the rotary cultivator has the advantages of compact structure, but the power consumption will increase sharply with the tilling depth increasing.
- the cutting soil resistance force direction of the knife cylinder points to the front top, and its vertical component force points upward, which will not be helpful for rotary tilling blades piercing soil.
- the blade back will squeeze soil when travel speed increase and leading rotary tillers to bump which influences the stability of tilling depth. If the horizontal resistance force of the knife roller is bigger than tractor rolling resistance and other horizontal resistances, the tractor will be pushed to slip in the process of cutting soil, and parasitic power will be generated. It will lead tractor driving system to be destroyed, increase tractor power consumption and lower tractor effective life.
- the submerged reverse rotary tillage is a rotary tillage model of the rotary cutter shaft sinking below the surface. Because the rotation direction of rotary blade is averse to the rotation direction of the driving wheel of the tractor, submerged reverse rotary tillers cut soil clods from the bottom of the furrow, and more soil clods are broken by tension. So, submerged reverse rotary tillage can reduce the cutting resistance force, cutting torque, and soil crushing energy consumption. In addition, since the cutter shaft is below the soil surface, the submerged reverse rotary tillage can be achieved deep tillage by using a short blade. But the submerged reverse rotary tillage makes so many soil clods be thrown to the front of rotary tiller blade rollers and leading hipping.
- a rotary tilling device with easier manufacturing properties, and more particularly it relates to an oblique submerged reverse deep rotary tilling device.
- the further object of this invention is to till soil regularly at high speed, makes more soil destroy by pulling force, and changes the trail of throwing soil clods. It is a still further object of the present invention to reduce re-tillage and power consumption significantly and increase tillage depth.
- the device mainly comprises a stander, a mounted frame, a gearbox and an oblique blade roller.
- This device has characters as follows: the gearbox is configured at the center of the stander; the power input shaft of the gearbox is linked with the power take-off (PTO) shaft of the tractor by a universal joint, and the angle between the power input shaft and the tractor advancing direction (V) is 110 ⁇ 125°; the power output shaft of the gearbox is a splined shaft, further, the ends of the power output shaft are connected with corresponding adjacent ends of the oblique blade roller shaft and equipped in the bearing of the bearing seat respectively.
- the bearing seat is fixed on the stander by bolts.
- the oblique blade roller includes regularly configured rotary blades.
- the oblique angle between the oblique blade roller and the tractor advancing direction (V) is between 55 ⁇ 70°.
- the tips of the rotary blade are bending toward tilled soil (or rightward soil).
- a column of side force balance blades, whose moving planes are paralleled to the rotation plane of the tractor driving wheel is equipped on the left end of the oblique blade roller.
- the angle between the rotating center axis of the side force balance blades and the oblique blade roller is between 20 ⁇ 35°, and the rotating axis of the side force balance blades is paralleled to the driving shaft of the tractor.
- the working of the oblique blade roller is oblique submerged reverse rotary tilling, namely the oblique blade roller shaft is located below 5 ⁇ 10 cm to the soil surface, and the rotating direction is the inverse rotating direction of the driving wheel when the tractor is advancing.

- the distance between adjacent rotary blade cutter head is 100 ⁇ 150 mm, and each cutter head installed on 2 ⁇ 3 rotary blades, The phase angle of the rotary blade mounted on the same adjacent cutter head is 60 ⁇ 90°.
- the length, blade thickness, the lengthwise portion width and the positive section width are 150 ⁇ 250 mm, 8 ⁇ 10 mm, 15 ⁇ 20 mm, and 80 ⁇ 120 mm, respectively.
- the power of the tractor is transmitted to the gearbox through the universal joint, and then the power output shaft of the gearbox drives the oblique blade roller to rotate inversely and cut soil from plow-sole.
- the rotation center of the oblique blade roller is located below 5-10 cm to the soil surface, and the rotating direction is the inverse rotating direction of the tractor driving wheel. Since the oblique blade roller is configured obliquely to the tractor forwarding speed in the horizontal plane, the rotating plane of rotary blades and the forward direction of the tractor form an angle. So, rotary blades have a component velocity along the axial direction of the oblique blade roller when it is cutting soil, making more soil clods destroyed by pulling force.
- the oblique blade roller is mainly made up of configured rotary blades whose tips bend to the same direction.
- the angle between the rotary tilling blade roller and the tractor advancing direction (V) is 55 ⁇ 70°, and the rotary blade tips are all toward the right side of the tractor advancing direction (V).
- Side force balance blades are installed to the left side of the oblique blade roller and used to balance the axial component force of the oblique blade roller.
- the working pattern of this invention is an oblique submerged reverse rotary tillage method, so there is no soil restriction on the top of the tilling soil clod. Meanwhile, due to cutting soil configured regularly, the right-side soil has been cut when the rotary blades soil begins tilling. The soil is mainly destroyed by tension force.
- rotary blades Since rotary blades have axial component speed, tilled soil clods will be destroyed mainly by rightward pulling force applied by rotary blades, and the tilled soil clods are mainly thrown to cultivated land.
- the rotary blades reduce a constraint surface when they cut soil but the right first-row rotary blades.
- the cutting soil starts from the plow-sole, and more soil is broken by tension force.
- the device has not only the characteristics of deep plowing, and also has a good effect of soil crushing, stable operation, low power consumption, but also makes more cut soil clods thrown to the tilled farmland, reducing re-tillage and energy consumption.
- the oblique blade roller can cut the soil beneath the gearbox and the bearing seat. So, the device can avoid the lower edges of the gearbox, and the bearing seat is interfering with the uncultivated land, making gearbox, bearing seat and a knife roller shaft easy to sink below the ground to achieve deep tillage.

- One part of the steel ball is fitted in this groove; the other part is fitted in the steel ball seat on the left side of the oblique blade roller.
- the steel ball seat is fixed with the cutter head by bolts.
- Side force balance blades are configured in the cutter head, and the side force balance blades rotating plane is paralleled to that of the tractor driving wheel.
- the knife roller shaft makes the steel ball seat rotate through the steel ball transmission, and the steel ball drives side force balance blades to rotate.
- the side force balance blades cannot only cut soil but also be used to balance the axial force of knife roller.
- the rotary blades cut soil with a component velocity along the axis of the knife roller. So, the present invention can make more soil destroyed by tension force than other rotary tillers.
- Rotary blades are installed on the cutter shaft, and their tips are all bending rightward, so they can cut soil regularly. In other words, the cutting soil clods reduce a rightward constraint face when they are tilling but those tilled by rotary blades configured in the first row. Thus, the soil can be more easily tilled, and consequently save tilling energy.
